本文執行個體講述了PHP實現產生資料字典功能。分享給大家供大家參考，具體如下：
最近時間緊迫，沒有時間發部落格，趁現在有點時間向大家分享一個知識點。在咱們做開發的時候 ，也許經常會遇到對資料庫分析，做一個資料字典，那麼現在好處來了，大家只需要關注我所發送的這個連結輕輕鬆鬆幫你們搞定資料字典的設計，再也不用你們下載資料字典那個工具，作為一個開發人員，隨便幾行代碼就應該會搞定這個知識，那麼現在廢話我也不多說了，大家看底下的代碼，大家只需要改一下你的資料庫帳號和密碼然後運行一下就可以了。
效果展示：
說了這麼多廢話了，終於開始寫代碼了：
<?php/*** 產生mysql資料字典*///設定資料庫$dbserver = "127.0.0.1";$dbusername = "帳號";$dbpassword = "密碼";$database = "資料庫";//其他配置$title = '資料字典';$mysql_conn = @mysql_connect("$dbserver", "$dbusername", "$dbpassword") or die("Mysql connect is error.");mysql_select_db($database, $mysql_conn);mysql_query('SET NAMES utf8', $mysql_conn);$table_result = mysql_query('show tables', $mysql_conn);//取得所有的表名while ($row = mysql_fetch_array($table_result)) { $tables[]['TABLE_NAME'] = $row[0];}//迴圈取得所有表的備忘及表中列訊息foreach ($tables AS $k=>$v) { $sql = 'SELECT * FROM '; $sql .= 'INFORMATION_SCHEMA.TABLES '; $sql .= 'WHERE '; $sql .= "table_name = '{$v['TABLE_NAME']}' AND table_schema = '{$database}'"; $table_result = mysql_query($sql, $mysql_conn); while ($t = mysql_fetch_array($table_result) ) { $tables[$k]['TABLE_COMMENT'] = $t['TABLE_COMMENT']; } $sql = 'SELECT * FROM '; $sql .= 'INFORMATION_SCHEMA.COLUMNS '; $sql .= 'WHERE '; $sql .= "table_name = '{$v['TABLE_NAME']}' AND table_schema = '{$database}'"; $fields = array(); $field_result = mysql_query($sql, $mysql_conn); while ($t = mysql_fetch_array($field_result) ) { $fields[] = $t; } $tables[$k]['COLUMN'] = $fields;}mysql_close($mysql_conn);$html = '';//迴圈所有表foreach ($tables AS $k=>$v) { //$html .= '<p><h2>'. $v['TABLE_COMMENT'] .
